The Empire Polo Club in Indio, Calif., will be graced again with a fiery-hot list of artists during the annual Coachella music festival, to be held April 15–17. In true Coachella fashion, festivalgoers will brave the desert-hot sun while being treated to a mash-up of artists from all across the musical spectrum. The lineup will feature current GRAMMY nominees Arcade Fire, the Black Keys, the Chemical Brothers, Cee Lo Green,Kings Of Leon, Mumford & Sons, and Kanye West. Other artists on the bill include Animal Collective, Duran Duran, PJ Harvey, Interpol, Jimmy Eat World, Lauryn Hill, the Scissor Sisters, and the Strokes, among many others. By July of last year, Coachella had made a name for itself as the top-grossing concert in 2010. So get your tickets early, and watch out for the birds flying overhead during KOL's set.

GRAMMY-winning songwriter Diane Warren isn't missing a thing lately. Fresh off her Golden Globe Award win for "You Haven't Seen The Last of Me" (sung by Cher in Burlesque), Warren has penned a song just for Best New Artist nominee Justin Bieber, "Born To Be Somebody," for his hotly anticipated upcoming 3-D film, Justin Bieber: Never Say Never. "It's a beautiful song," said Warren at a Golden Globe Awards after-party last Sunday. "That's a good age difference between Cher and Justin — 40 years!" Is the song born to be a hit? The odds are favorable, with Warren having written a list of hits for other artists, including Celine Dion's "Because You Loved Me, " Toni Braxton's "Un-break My Heart," Aerosmith's "I Don't Want To Miss A Thing," and Belinda Carlisle's "I Get Weak," among others. Justin Bieber: Never Say Never will be in theaters on Feb. 11. Don't miss it....

Green Day's Billie Joe Armstrong has decided to take a break from his starring role in the Broadway musical "American Idiot" and Melissa Etheridge seems to be the only one to fill the punk rocker's heavy shoes onstage. Etheridge will reportedly fill in for Armstrong from Feb. 1–6, playing the drug dealer named St. Jimmy. "This character is seductive, thrilling and dangerous," said director Michael Mayer. "Melissa Etheridge is all that and so much more." In contrast to what the title song may say, Etheridge does want to be an "American Idiot." We can only hope Armstrong is back by his expected return date of Feb. 10 because we certainly wouldn't want to wait until September ends.

The hit TV show "Glee" may have notched a GRAMMY nomination this year, but it won't be taking a trip to the "Paradise City" anytime soon. Former Guns N' Roses guitarist Slash said that the group turned down the show's request to use GNR's music in an episode. "We got asked about that once already but it got turned down," said Slash. "In the current climate of what's going on in entertainment these days, I try to be more optimistic than negative because it's really easy to get negative about it, but I draw the line at 'Glee.'" In related news, GQ magazine drew their own line at GNR frontman Axl Rose, who was included on their 2011 worst-dressed list. "It's high time Rose left his clothes out in the November rain," said GQ.

His songs have stood the test of time but can his novels? Singer/songwriter legend Bob Dylan has reportedly signed a six-book deal with publishing company Simon & Schuster. While the deal has yet to be confirmed, it will reportedly bring to fruition two more volumes of Dylan's Chronicles memoir series and an additional book based on his XM Satellite Radio show, "Bob Dylan's Theme Time Radio Hour." There are reportedly three additional "unspecified" books that could also be part of the deal. We've taken a few wild guesses as to some potential titles: Bob Dylan's Jingle Jangle Mornings, Confessions Of A Tambourine Man and I Can't Write.

If Sting were to write "If You Love Somebody Set Them Free" today, he'd likely be writing a hit song about dolphins in Japan. After viewing The Cove, a documentary on the annual killing of dolphins in Taiji, Japan, Sting has etched these dolphins into his environmental and humanitarian philanthropy plans and wants to help save the mammals. "I was blown away by the movie," said Sting. "We should not be eating dolphins." Sting, along with wife Trudie Styler, will plan to get the word out on animal cruelty issues "through dialogue." Will this mean a new album titled 11 Dolphiner's Tales? We're not sure, but we can be sure that Sting is very passionate about finding a solution. "We only evolve as a species when we are in crisis," said Sting. "We don't want an empty sea."

Will award shows now be going digital too? MTV is planning to launch a multiplatform award show this spring that will honor digital music via a "multiscreen experience" involving the Internet, social media and mobile platforms — but not via a broadcast. The exact concept and titles of the awards have yet to be defined, but best apps, blogs and tweets are likely to be represented. (Kanye West will likely be a frontrunner in the latter category.) Whatever it turns out to be, the show will be "an interactive musical mess" celebrating "the cool and the geekdom," according to Van Toffler, president of MTV Networks Music and Logo Group.

Britney Spears' "Hold It Against Me" is tops on both the Billboard Hot 100 and iTunes singles chart.
